wouldn't go quite that far!
Had a quick trial run of the bottom half of the cooler this weekend.
Started off by waxing the three bits of the mold and then clamping them together. If you're not worried about the finish of the component, you can rub candle wax over the mold surface and the part will release dead easy. For a beld'n'braces approach, I coated it with PVA release agent too.
Next up is to plug the seams so that resin doesn't get in there and glue the mold sections together. This is just plasticine but for the final parts I'll be silicone sealing the sections together as I need them to be air tight.
And here's the result of a very quick and not especially thourough laminate of two plies of glass. Final produce will be 4 plies of carbon and one of diolen. This bit isn't much to look at, but it let me prove the molds release properly and I can use it to determine how long the trumpets need to be.
Also let me check that the hose joiners actually fit! And also that there's enough room for a trumpet there.
In other news, bought a little electric sander just to speed up the recovery of the top half of the mold. Hoping to get that finished this evening and then make a dummy top half so that it can all go under the bonnet to check for fit.
Last but not least, here's the dummy bottom half with the cores in it:
